Bark

Bark is a transformer-based text-to-audio model created by Suno. Bark can generate highly realistic, multilingual speech as well as other audio - including music, background noise and simple sound effects. In this template we will import Bark into Inferless Platform.

Deploy Bark using Inferless:

• Deployment of Bark model using bark.
• By using the bark, you can expect an average latency of 4.29 sec.

Prerequisites

• Git. You would need git installed on your system if you wish to customize the repo after forking.

• Python>=3.8. You would need Python to customize the code in the app.py according to your needs.

• Curl. You would need Curl if you want to make API calls from the terminal itself.

Quick Start

Here is a quick start to help you get up and running with this template on Inferless.

Fork the Repository

Get started by forking the repository. You can do this by clicking on the fork button in the top right corner of the repository page.

This will create a copy of the repository in your own GitHub account, allowing you to make changes and customize it according to your needs.

Create a Custom Runtime in Inferless

To access the custom runtime window in Inferless, simply navigate to the sidebar and click on the Create new Runtime button. A pop-up will appear.

Next, provide a suitable name for your custom runtime and proceed by uploading the inferless-runtime-config.yaml file given above. Finally, ensure you save your changes by clicking on the save button.

Import the Model in Inferless

Log in to your inferless account, select the workspace you want the model to be imported into and click the Add a custom model button.

• Select Github as the method of upload from the Provider list and then select your Github Repository and the branch.
• Choose the type of machine, and specify the minimum and maximum number of replicas for deploying your model.
• Configure Custom Runtime ( If you have pip or apt packages), choose Volume, Secrets and set Environment variables like Inference Timeout / Container Concurrency / Scale Down Timeout
• Once you click “Continue,” click Deploy to start the model import process.

Customizing the Code

Open the app.py file. This contains the main code for inference. It has three main functions, initialize, infer and finalize.

Initialize - This function is executed during the cold start and is used to initialize the model. If you have any custom configurations or settings that need to be applied during the initialization, make sure to add them in this function.

Infer - This function is where the inference happens. The argument to this function inputs, is a dictionary containing all the input parameters. The keys are the same as the name given in inputs. Refer to input for more.

def infer(self, inputs):
    prompt = inputs["prompt"]

Finalize - This function is used to perform any cleanup activity for example you can unload the model from the gpu by setting self.model = None.

For more information refer to the Inferless docs.
